Hi All,

       I have the following code from 

https://documentation.sas.com/doc/en/pgmsascdc/9.4_3.5/mcrolref/p1hogk0ekd1z62n18xx76ou16unt.htm

Please, help me to understand why fread is reading only John from the file and not entire record. How to make fread to read entire row of each observation?

 

%macro test(outf);
%let filrf=myfile;
%if %sysfunc(fileexist(&outf)) %then %do;
%let rc=%sysfunc(filename(filrf,&outf));
%let fid=%sysfunc(fopen(&filrf));
%if &fid > 0 %then %do;
%let rc=%sysfunc(fread(&fid));
%let rc=%sysfunc(fget(&fid,mystring));
%if &rc = 0 %then %put &mystring;
%else %put file is empty;
%let rc=%sysfunc(fclose(&fid));
%end;
%let rc=%sysfunc(filename(filrf));
%end;
%else %put file does not exist;
%mend test;

 

/*Calling the above macro*/

%test(c:\Address.dat)

 

Output in the log:

%test(c:\Address.dat)

John

 

The contents of test.dat are as follows:

John Garcia            114 Maple Ave.
Sylvia Chung      1302 Washington Drive
Martha Newton    45 S.E. 14th St.

 

 

Thanks

By default FGET reads to the first space, so it only read John and not beyond.

 

If you use another argument — the LENGTH argument — in the FGET function, you can tell it to read more. https://documentation.sas.com/doc/en/pgmmvacdc/9.4/lefunctionsref/p1a70mpbj2usaln1r9z4qldliexk.htm

Thank you very much PaigeMiller. I have used length now and it's working.
